In this final chapter, we will be building a complete web application from scratch with Koa. This will help us to reinforce our learning and make use of concepts we have learned in a real-world application. 

We will make use of all the concepts learned in previous chapters to build an end-to-end monolithic application in Koa.

Some of the things we will learn in this chapter include:

• How to build an end-to-end application from scratch with Koa
• How to handle sessions in Koa
• How to handle authentication in Koa
• How to create views and work with templates in Koa
• How to work with form data in Koa
